Question for my on info - What are cab files? I thought these were just back ups of my original computer comfiguration (or last saved configuration) and in case of problems I can get my computer to its previosu state state. But when I received your recommendations, I had to clean some can files too. Was this recommendation to make sure that i wont reinstall the erased trojans/spyware in case I use the backup files in case of a problem? Or am I totally wrong in what I was thinking about Cab files?
